Specification of Letters Patent.

Application filed February 24, 1919. Serial No. 278,965.

To aZZ whom t may concern.'

Be it known that l, MiTsUJi TA'riioizA, a subject of the Emperor of Japan, residing at Gardena, in the county of Los Angeles and State of California, have invented a new and useful Broeder, of which the following is a specification.

This invention relates to improvements in brooders and similar substitute devices for a hens wings, and its objects are to provide a uniformly heated housing space, efficient ventilation thereof, and means for varying the inclosed space and expanding the limits thereof, all in accordance with the size of the brood of chickens therein.

Brooders as heretofore constructed are provided with but one entrance or opening which serves for ventilation. It frequently occurs that the chickens will crowd together in front of the entrance, resulting in suifocation of some of them, and no accommodation can be made for the size of the brood, therefore requiring when the chickens are small, a proportionately greater heat maintenance therein.

These objections have been overcome by.

providing means for varying the volume of inclosed space, locating the heating means in a separate inclosed compartment, and providing a plurality of Ventilating apertures in the space inclosing walls thereof.

Other objects are to provide means embodying sanitary and economical features. By my provision of removable and adjustable top and sides, it is possible to make the brooder perfectly clean and free from germs n with a minimum expenditure of time and trouble.

Upon the annexed drawings, Figure 1 is a longitudinal and sectional view of a brooder embodying my improved construction. Fig. 2 is a perspective view of a dei tachable side wall. Fig. 3 is a plan of a chicken yard with the brooder adjacent thereto. Fig. 4: is a perspective view of the brooder showing the cover open for ventilation. Fig. 5 is a perspective view of a slide cover.

Referring more particularly to the drawings, the heater 11 is contained within a separate compartment 12, adjoining the hovering compartment 18. The heater 11 is further inclosed by a cylindrical member 111 forming a jacketed space 15, having openings 16 at the bottom, and connected at the top with a pipe 17, extending to the hovering compartment. With this arrangement, the brooder, after once being heated to the proper temperature, will not be affected by extremes of variation in the heat produced by the apparatus.

The compartment 13 is provided with a detachable cover 1S, having hingedly connected leaf sections 19, which maybe turned to open position for ventilation. rlhe end walls 20 are integral with the bottom 21. Entrance openings 22 are provided and are adapted to be closed by slide doors 23, the slide doors being provided with swing doors 24, and may be shifted to accommodate the doors 24 to the` inclosed space. Two entrance openings are provided so that one may always serve as a ventilator regardless of the position of the chickens within the brooder. Apertures 25 serve as ventilators.

rIhe side walls 26 are arranged to form the right and left walls of the brooder, and are adjustable to and from the center to -vary the inclosed space. The members 26 are formed with vertical walls 27, provided with Ventilating apertures 28 and light wells 29. The top walls 30, are provided with screen covers 31. These may be raised or opened for removal of the chickens if desired. The detachable cover 18 is adapted to extend over the screen covers for retaining the heat within the brooder, or may be placed in open position. A ventilator 32, constricted as it approaches the top 33, is arranged with the bottom opening 34 adjacent to the bottom 21. The heating means consists of a steam radiator pipe 35, extending longitudinally and centrally within compartment 13, the coils being arranged to form a sinuous and inclined heat conductor, efficient for im proved circulation of the heating medium.

From the foregoing it may be seen that I have provided eflicient means for varying the limits of the space within the hovering compartment, and the device may therefore be adjusted to the size of the chickens and the number comprising the brood. The de-v vice is increased in capacity by pulling out the side wall members. The entrance, shown in dotted lines in Fig. 1, is covered by the slide 28, retained by the guide members 36 and 37, the slide being adjusted in accordance with the limits of the inclosed space. For cleaning purposes, the top cover and side wall members may be temporarily shifted so that one-half of the bottom is exposed. The inclined conductor and radiator pipe insures that the condensed portion of the steam orheating medium will be promptly returned to the heater.

What is claimed is:

l. In a brooder, an integral casing consisting of a bottom and two end-walls, heating pipes disposed longitudinally above the bottom and extending between .the end-walls, sideewalls adjustable to Vand from the'heating pipes to inclose a variable space, and a sectional top adjustable to cover the space inclosed by the side and end-walls.

2. In a broeder, integral bottom and end walls, a detachable top adjustable to cover a variable area, a heating coil disposed longitudinally between the end walls, and side walls extending between the end-walls and adjustable to and from the heating coil.

3. In a brooder, a bottom and integral end walls, said end walls having entrance openings, a folding top, movable side walls adapted for varying the inclosed space, slides to cover the entrance openings in accordance with the inclosed space, and swing doors in the slide members whereby two entrance openings are maintained.

4. In a brooder, adjustable walls inclosing a hovering space, and movable to vary the space limits, rectangular openings in cer tain of the inclosing walls, slide members tocover kthe rectangular openings, and openings in the slide members whereby the entrances are maintained at opposite corners of the inclosed space. 5. In a brooder, integral bottom and end walls, a oldable and detachable top, movjusted in accordance with the capacity of the space inclosed by the top, end walls, and side walls, and openings in the movable closure members providing entrances adjacent to the side walls.

6. The combination with an integral bottom and end-walls, and rectangular openings in the end-walls, of a heating coil disposed above tlie bottom and extending between thev end-walls, side-walls movable to and from the heating coil and inclosing a variable floor space, a topi foldable in sections and adapted to cover the variable space and area inclosed by the side-walls and endwalls, slide members: forming closures for the rectangular openingsv in, the end-walls, and entrance openings in the slide members, said slide members being adjustable to place the entrances adjacent to the side-walls.

In testimony whereof, I hereunto affix my signature.
